Yes, and you should read the above text in context, and have a working
understanding of the ffmpeg processing fundamentals (hint: bitstream
copy and filtering is not possible at the same time, please read the
fine introductory part of the ffmpeg manual).

...

I think we should warn and/or abort in case filtering and copy is
enabled at the same time, in order to spare such reports and save some
time to both us and users.

I believed there was an open ticket about this but I was probably
wrong as I couldn't find it.
